This is part one of a two-part series. Here, we look at why SBOMs matter for software quality assurance. In the next post, we’ll walk through how to put them into practice. If you work in QA and want to explore this further, feel free to reach out.

In regulated sectors like banking, fintech, healthcare, insurance, and automotive, software quality isn’t just about functionality — it’s about risk, compliance, stability, and auditability.

Yet most QA organizations still focus heavily on tests, automation, and defect management, while remaining blind to what’s inside the software itself.

That’s where Software Bills of Materials (SBOMs) are transforming the QA function.

Regulated Industries Demand More Than Traditional QA

A QA lead in a bank or healthcare system must ensure:

  • Stable releases
  • Predictable behavior across integrations
  • Compliance with internal and external audits
  • Minimal production failures
  • Traceability for every release

But traditional QA only tests behavior. SBOMs add visibility into the components powering that behavior.

What SBOMs Give QA That Testing Alone Cannot

An SBOM (Software Bill of Materials) provides a comprehensive inventory of third-party and open-source components in the software — including versions, dependencies, and lifecycle status. While completeness varies by SBOM format (SPDX, CycloneDX) and generation method, modern SBOMs capture the critical components QA needs to assess.

For QA, this means immediate insights into:

Component Quality

  • EOL/EOS components that can break after platform upgrades
  • Stale libraries lagging behind current releases
  • Multi-version drift across microservices/applications
  • Fragile or unmaintained packages

These factors often contribute to regression failures and production instability, particularly during platform upgrades or dependency updates.

Security-Driven Quality

In regulated industries, vulnerable components are a quality problem, not just a security issue.

SBOMs highlight:

  • KEV (Known Exploited Vulnerabilities) - vulnerabilities actively exploited in the wild
  • High EPSS scores - Exploit Prediction Scoring System indicators showing components likely to be targeted
  • Integrity anomalies - publisher mismatches, unsigned packages, supply chain risks

Upgrades triggered by these risks expand QA scope — SBOMs help QA plan for it.

Compliance Quality

Regulators expect full transparency in the software supply chain.

SBOMs help QA ensure:

  • License compliance - identifying copyleft licenses (AGPL, GPL) and restrictive licenses (SSPL) that may conflict with corporate policies
  • Complete audit trails of components per release
  • Evidence of component versioning and patch levels
  • Attestation and signing coverage for supply chain security

This reduces audit friction and rework.

Why SBOMs Matter Specifically for QA Leads

More predictable regression planning

SBOM insights show where upgrades or breakages are likely, allowing QA to adjust test depth early.

Stronger release governance

SBOM-based quality thresholds (EOL %, KEV presence, license issues) can become part of QA’s go/no-go criteria.

Fewer production incidents

Component-related production failures (outdated dependencies, version conflicts, EOL libraries) become preventable when SBOM monitoring detects these risks before release.

Vendor and third-party risk visibility

Regulated industries rely heavily on vendor software. SBOMs reveal dependency risks inside vendor deliverables — no more black-box assumptions.

Improved audit readiness

SBOMs provide the component-level evidence auditors expect for compliance frameworks like RBI, NIST, ISO 27001, HIPAA, and ISO 21434.

SBOM = The New QA Quality Layer for Regulated Industries

Regulated software teams are starting to treat SBOMs as a complementary artifact similar to a test plan or traceability matrix.

Functional testing validates behavior. SBOMs validate the integrity, safety, and reliability of the components behind that behavior.

Together, they create a more complete quality picture and reduce the operational and regulatory risk of every release.

The Future of QA in Regulated Industries Is SBOM-Aware

As systems grow more interconnected and regulators demand deeper transparency, QA’s role is shifting from testing functionality to assuring holistic software quality.

SBOMs elevate QA from:

  • Reactive → Predictive - anticipating component-driven issues before they manifest
  • Function-focused → Component-aware - understanding both behavior and composition
  • Audit-chasing → Audit-ready - maintaining continuous compliance evidence
  • Siloed → Aligned - collaborating with security, dev, and compliance teams

In banking, healthcare, fintech, and automotive, SBOMs are quickly becoming as essential as test cases and traceability matrices.

A modern QA Lead doesn’t just validate the software — they validate the supply chain behind it. SBOMs are how they do it.
